Latest Patents

David F. Johnson holds a patent for a "Programmable Logic Array Adder." This invention discloses a multi-digit binary adder that is embodied in programmable logic arrays (PLAs). The specific programmable logic array utilized features a separate two-bit decoder for receiving each pair of digits A.sub.i and B.sub.i from two n-digit binary numbers. The decoders generate output signals known as min terms for each possible combination of the true and complement of each digit pair. These min terms are then processed by an array called the product term generator or AND array, which generates the necessary product terms for binary addition. He has 1 patent to his name.
